LIGHTNING-ARRESTER.

Specification of Letters Patent.

Patented Nov. 17, 1914.

Application filed April 27, 1914. Serial No. 834,602.

Taall whom t may concern.'

Be it known that I, HENRY M. PINGEN, residing at Toledo, Lucas county, Ohio, have filed my first papers for citizenship in the United States of America and have invented new and useful Lightning-Arresters, of which the following is a specication.

This invention relates to lightning arresters for electric conductors.

This invention has utility when incorporated in connection with a conductor to protect the conductor from high voltage disturbances.

Referring to the drawings: Figure 1 is a side elevation of an embodiment of the invention in a cartridge form of lightning arrester; Fig. 2 is a vertical longitudinal section of the device of Fig. l; Fig. 3 is a section on the line III- III Fig. 2 looking in the direction of the arrow; Fig. 4 is an end elevation of the device of Fig. 1; and on section line II-II, looking in the direction of the arrow, shows the line of section of the showing in Fig. 2.

rThe device may be placed in circuit for the protection of an electrical conductor by the wire 1 extending from the line to be protected to the terminal 2 in the insulating base 3, said terminal 2 being connected through said base with the spring arms or clip 4. The opposite end of the block 3 is provided with similar spring arms 5 in electrical communication with the terminal 6 from which the line 7 may extend to ground.

The device proper may comprise a cylindrical member 8 say of glass which may have inwardly extending ribs 9. In assembling the device, washers 10 may be spaced by the tube 1l say of porcelain to bring the washers 10 in the region of these inwardly extending ribs 9.y This porcelain tube 11 is thus centrally disposed within the outer glass tube 8 and there is formed between these tubes a surrounding or outer chamber while within the tube 11 is the irst or inner chamber in communication with the outer chamber by the openings 12. Within the inner chamber is disposed the terminal 13 which may be of metal and the terminal 14 which is of a dissimilar substance say of carbon mounted on the good conductor element 15. There is accordingly provided within the inner chamber the pair of opposing terminals 13, 14, which may be spaced as desired in the construction of the device as determined by the work for which the designed.

The device is sealed or may be gas tight as to the two chambers by forcing about the conductors 13, 15, yieldable Stoppers 16 say of rubber against the washers 10 and the inwardly extending ribs 9. These Stoppers 16 are sealed by an insulating compound 17, second Stoppers 16 placed in position thereover and the sealing operation repeated. These steps may be alternated to fill the glass tube 8, when the terminal caps 18 may be cemented thereon and additionally held in position by the bolts 19 engaging the conductors 13, 15, so that when the cartridge is in position to be engaged by the yieldable clips 4, 5, these caps 18 through the bolts 19 readily conduct to the elements 13, 15. With the device thus assembled and thoroughly sealed exhaustion of the chambers may occur laterally of the tube 8 and the tube sealed at the projection 20. To avoid danger of breakage, the cap 21 may be cemented on this projection 2O and the cartridge when placed in position may dispose this projection toward the insulation block 3. The ex'- haustion of the chambers as well as the positioning of the terminals 13, 14, may be such as to answer the particular voltage requirements and amperage needs of the installation for which the device is designed. The structure is of such a character that it is possible to design the apparatus for protection 0f a line of every heavy normal carrying capacities.

In the placing of the arrester there is provided a supplementary device or shield, herein shown as comprising clips 22 embracing the caps 18 between the clips 4, 5. These spring clips 22 have integral arched extensions 23 extending toward each other .and spacedA by the insulation section 24 to form an air gap therebetween.

In testin out the device with an induction coil, w en there is an arcing across the gap 24 the lightnin arrester is out of order for Jthe resistance o this smaller gap 24 in air is greater than the lower pressure but further spaced gap between the terminals 13, 14. Accordingly in testing the device with an induction coil and with no spark occurring at the gap Q4, the jump occurs between the terminals 13. 14. By providing the terminal 14 of different material, as carbon, there is not the danger of holding particular apparatus is Q minacce the are and thus. getting the. apparatus ont of Orderi...

lThe utility of the double chamber-'feature is in protecting the glass or outer chamber walls from the heat of the arc or spark and there is a further quenching action iin-that the smallopenings l2 allow the arc supportgasain-the inner chamber to-becom'e exhausted before there may be an iniiowing `sup ly from the outer chamber. However,

.as t e intervalipasses, the gases in the two chambers readjust themselves automatically .andthe apparatus is accordingly in condition to stand many discharges-therethrough fand still be in good working condition.

What is claimed and it is. desired to se- 4cure by Letters Patent is:

, '1. An electric protective :device embody- .ing a cylindrical member, a pair of o posing electrically independent terminals t erelin, one entering from each end of the member, and a seal for each end of the cylindrical member including .yicldable Stoppers and cement for the Stoppers. Y

2. An electric protective device embodying a cylindrical member provided with a `pair of annular inwardly extending ribs, a pair vof terminals in said member, and a seal for the member. including opposing rubber Stoppers each movable to seat against a rib.

3. An electric protective device embodying a pair of terminals, arst chamber for said terminals, and a second chamber, there being a passage therefrom affording communication with -said rs't chamber, said chambers being 'gas tight..

4. An electric protective device1 embodying a pair of terminals, a, iirstchamber for said terminals, and a second surrounding chamber-,there being a passage therefrom aii'ording communication with said first chamber, said chambers being gas tight.

5. electric protective device having a pair of spaced terminals, an armored porltion adjacent jeachterminal, `an insulating section between'the armored portions, and an embracing shield for theinsulating section.

section between the armore an embracing sectional shield for the insu- -lating section.

" it. An electric protective devicev embody- 5c ing a cartridge lightning arrester" having a. pair' of spaced terminals, an armored portion adjacent each terminal an insulating section vbetween the armored portions, and an embracing shield or the insulating section.

'7. An electric protective device embodying a caitridge lightning arrester having a pair of spaced terminals, an armored portion adjacent each terminal an insulating d portions, and

8. An electric protective device embody- -ing la cartridge lightning' arrester and an ing action of instantaneous arcing between the electrodes extending to the second chamber, and means for determining the fluid content of said chambers. c

ll. An electric protective device embodying a pair of opposing electrodes, an inner chamber surrounding said electrodes, an

outer chamber enveloping the inner chamber, there being a passageway between said chambers precluding transmission of action from instantaneous arcing 'in the inner chamber extending to the outer chamber, and means for determining the iuid content of said chambers. i

In testimony whereof I hereunto set my hand in the presence of two witnesses.
